[RFC Aufs2 #3 0/2] 'debug' module parm and /sys/fs/aufs entries

[J. R. Okajima]

Some entires under /sys/fs/aufs still print an abosule path. While sysfs
(and procfs?) limits the length of an entry upto PAGE_SIZE, the abs path
can be any length. I don't think it is important to support longer path
than PAGE_SIZE, so aufs simply returns -EFBIG (regardless this patch).

Following the comments from Greg KH, split /sys/fs/aufs/si_<id>/xino
into some files in order to keep "one value per file".

J. R. Okajima (2):
  replace /sys/fs/aufs/debug by /sys/module/aufs/parmaters/debug
  split 'xino' entry under sysfs
